Filed Oct. 9, 1963, Ser. No. 315,058 2 Claims. (Cl. 15229) The competition in the manufacture of mops, under present conditions is very keen, and it is necessary, not only to improve the product, but to reduce the cost of manufacture.

The object of this invention is to devise novel means to interlock the mop material with a collar, which might serve as a grasping handle, and which in the present case, is internally threaded to receive the threaded end of a mop handle.

With the foregoing and other objects in view, the invention comprehends the novel construction and arrangement of the component parts for permanently interlocking the mop material with a collar, which may be adapted to receive a handle.

For the purpoe of illustrating the invention, I have shown in the accompanying drawings preferred embodiments of it, which in practice will give reliable and satisfactory results. It is, however, to be understood that I am not limited to the precise arrangement of the instrumentalities described herein, except by the scope of the appended claims.

FIGURE 1 is a perspective view of a mop embodying my invention.

FIGURE 2 is an exploded perspective, partly in section, showing the parts in the process of being assembled.

FIGURE 3 is a top plan view of the collar.

FIGURE 4 is a section on the line 44 of FIGURE 3, with the locking U-shaped spring clip in clamped position with the collar and mop strands and with the collar secured to a handle.

FIGURE 5 is a bottom plan view of the collar.

FIGURE 6 is a section on the line 66 of FIGURE 3, showing the U-shaped spring clip and mop strands being assembled with the collar.

FIGURE 7 is a view similar to FIGURE 6, but with the spring clip fastening means shown in its locked position.

FIGURE 8 is a top plan View of another embodiment of the collar.

FIGURE 9 is a perspective view of another embodiment of the spring clip fastening means.

FIGURE 10 is a perspective view of still another embodiment of spring clip fastening means shown inserted in a sponge type mop.

Similar numerals of reference indicate corresponding parts.

Referring to the drawings:

The component parts of the mop are mop material 1, which forms the mop head, a U-shaped spring clip 2 which interlocks with a collar 3, and the collar 3 which is adapted to receive a handle 4.

The mop material 1 may be of a character for wet or dry cleaning and is shown in FIGURE 1 as spaghetti type strands in the form of fabric tubes containing an absorbent material such as cotton, or any other desired absorbent or abrasive material. The U-shaped spring 2 has the end portions of its side arms reversely bent to form spring members 5.

"ice

The collar 3 has at opposite sides, longitudinally disposed holes, 6 and 7, parallel to each other. The holes are of a uniform size for a portion of their length and rectangular in cross section throughout, but are of an enlarged size as at 8 and 9, thereby forming shoulders 10 and 11.

In order to better balance the construction, the reversely directed spring members 5, at opposite sides are directed in opposite directions, although as will later appear, the spring members may extend in the same direction.

In the operation of this form of the invention as shown in FIGURES 1 to 7, the mop material is assembled in the U-shaped clip, preferably centrally thereof, and the spring members 5 are pushed into the holes 6 and 7 at one end of the collar at which the holes are of less length than the opposite end. When the U-shaped clip is moved into the holes a sufiicient distance to permit the free end of the spring members to pass beyond the shoulders 10 and 11, the spring members 5 spring outwardly and contact the shoulders to permanently lock the mop head to the collar.

The collar is internally threaded as at 12, to contact the threads 13 of the handle 4.

The embodiment seen in FIGURES 8 and 9 shows the U-shaped spring clip 14, having reversely bent spring members 15 and 16 of the side arms, directed in the same direction to contact shoulders 17 and 18 in collar 19.

In the embodiment shown in FIGURE 10, the mop head material 20 is shown as of block formation and may have absorbent or abrasive characteristics or capable of use as a dry mop or dust mop and is secured to the collar by a U-shaped clip 21 in the form of a band having the free ends of its side arms reversely bent to form spring members 22 and 23 adapted to interlock with the shoulders in the collar, it being apparent that the holes in the collar would be of suflicient size to receive the spring members 22 and 23.

In the assembly the U-shaped clip containing the mop material may be forced into locking engagement with the collar by an arbor press, or any other desired means.

The collar may be formed of molded plastic or any other desired material.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A mop comprising a collar having at opposite sides, longitudinally extending holes rectangular in cross-section, said holes being of less length at their lower portions than at their upper portions, thereby forming shoulders, a substantially U-shaped spring clip having its arms including the free ends thereof reversely bent to form spring locking members, mop material within said spring clip, said spring clip arms extending into said holes with their free ends contacting said shoulders and a handle connected with said collar.

2. The means defined in claim 1, wherein the reversely bent portions of the U-shaped spring clip are bent in opposite directions.
